  • Publication number: 20120016756
    Abstract: A system for providing distributed control to process transactions is disclosed. The system includes a service provider system having associated therewith a number of rules and a number of meta-rules, a point of service device having associated therewith a number of rules and a number of meta-rules, and a portable device having associated therewith a number of rules and a number of meta-rules. The portable device uses its associated rules to determine an outcome for a transaction. If the portable device is unable to determine the outcome for the transaction, the portable device uses its associated meta-rules to either determine whether one or more of its associated rules can be altered locally in order to determine the outcome or request the point of service device to help determine the outcome using the rules and meta-rules associated with the point of service device.

  • Publication number: 20110204096
    Abstract: An actuator/closing element combination for a dispenser of a dispensing system for flowable washing or cleaning agents includes a closing element in the form of an open/close valve element, and an actuator coupled to the closing element in such a manner that the closing element may be displaced by the actuator into a closure position and into a passage position, the actuator being configured such that, when driven by an appropriate pulse, it determinably occupies alternately one of two end positions and, without actuation, stably retains the end position reached, such that the actuator/closing element combination forms a pulse-controlled, bistable open/close valve.

  • Publication number: 20110191155
    Abstract: A method of processing data on a server computer is disclosed. The method includes receiving data at the server computer, the data including a first data string including one or more wildcard values. The first data string is specifically associated with a customer, and the one or more wildcard values are associated with the purchase transaction. The method also includes comparing the first data string to a second data string by the server computer, and providing an output to the consumer based on the comparison.

  • Publication number: 20110139820
    Abstract: A dispensing system for the interior of a dishwashing machine includes a component carrier on which components are detachably or nondetachably arranged, including at least a dispensing chamber, an actuator, and a closing element as well as an energy source and/or a control unit and/or a sensor unit. The closing element is coupled with the actuator such that movement of the actuator displaces the closing element into a closure or a release position. The at least one dispensing chamber is connected in communicating manner with at least one cartridge chamber and includes an inlet for inflow of washing or cleaning agent from a cartridge chamber and an outlet for outflow of washing or cleaning agent from the dispensing chamber into its surrounding environment. The outlet of the dispensing chamber is closable or openable by the closing element.

  • Patent number: 7857216
    Abstract: A system for facilitating image management for portable devices, which includes a host configured to maintain information relating to a first portable device and a second portable device and an interface device configured to communicate with the host and the portable devices. The interface device includes control logic configured to: determine whether the first portable device is valid for image synchronization using information provided by the host in order to record an image of the first portable device, determine whether the second portable device is valid for image synchronization in order to download an image of the first portable device to the second portable device. The interface device further includes control logic configured to: determine whether the second portable device is valid for image replacement using information provided by the host so as to retrieve an image of the first portable device and download the retrieved image to the second portable device.
